Repotting indoor plants

hi all:)

ive got quite a big collection of indoor plants that i got in the last couple of years and i’ve recently had to repot my umberella plant and my alocasia zebrina and a couple of cacti however i still feel relatively new to repotting with those the only ones ive ever done.
I was wondering if anyone could tell me if these few plants in the pictures need repotting and how much bigger of a pot they should be transplanted into. 

This is my aloe vera plant, there’s no roots coming through the bottom of the pot but it does seem really big for the pot now?

This is my dieffenbachia’s roots.

My birds nest fern used to be really healthy looking and green but the bottom leaves have started turning yellow and brown so was just wondering if it’s due for another repotting or whether it’s just not getting enough light in the bathroom.

And lastly, this is one of the cactus that i recently got, the roots are starting to come through the bottom.

would appreciate any advice!

    I am not sure about your more succulent plants I killed off most of the ones we used to have.
    However, the Birds nest fern don't worry, that is normal,  they are the oldest leaves on the outside and they do slowly die off. Remove them as and when they get tatty or discoloured and new ones will come more quickly in the centre.
    If you have not repotted recently or if the roots don't fill the pot a feed will help it along.

    I think that repot the ones with roots coming through the bottom if they are getting compacted or close together in the pot. But do not over pot them. I think the mistake people make is sometimes doing it too soon or a pot that is too large so the compost gets soggy and sour before the roots can fill it. I hope that makes sense.
  • @Rubytoo thank you for the advice!! It took me ages to stop killing my succulents and cacti too lol!

    I don't repot at this time of year as most plants especially cacti are dormant. Leave it until Spring. Good advice already given is don't overpot either on smaller pots I go up about a half inch each side or if over 6 inches across I'd go up an inch each side. 
    Youll need regular compost for house plants plants but a grittier one for cacti and succulents which need good drainage. 
  • thank u for ur help @Bilje :)

    When you do repot the cactus I would remove all that loose soil from the top to expose the base of the plants and then replace that with grit. For now I'd water from the base of the pot and don't let it soak up to the top layers or you might be risking rot problems.
    The first thing I do with shop bought plants now is brush out the loose soil and refresh it. The nursery soils always seem to go mouldy really quickly and it helps get rid of any bugs too.
    Tradition is just peer pressure from dead people
